The Dynamic Tower

I was surprised at the news of Dubai's new skyscraper, The Dynamic Tower. I cannot believe that each floor of the building can rotate independently from the other and besides that the building will be 420 meters high. Each floor spins 360 degrees which would mean the building is supported by only a column. If an earthquake broke out there, would the rotating tower be safe enough? Of course, the design must be safe but I would not want to live in the new skyscraper if I had enough money to live there.
